地处雷雨多发地区的仪表着陆系统台站,虽然在安装之初都配备了防雷系统,但在每年的雷雨季节遭受雷击的概率依然很大。对于仅有一条跑道运行,甚至只配备了单向仪表着陆系统的机场,一旦遭受雷击,将直接影响到航班的正常着陆,给空中交通管制,机场,航空公司等部门带来很大的压力。本文从某台站遭受雷击故障检修出发,探讨对防雷系统的改进措施,避免类似情况的发生。
The instrument landing system station in a thunderstorm-prone area, although equipped with a lightning protection system at the beginning of installation, is still at a high probability of being struck by lightning every year during the thunderstorm season. For an airport running on only one runway or even a one-way instrument landing system, once it is struck by lightning, it will directly affect the normal landing of the flight and put a lot of pressure on air traffic control, airports, airlines and other departments. This article from a station suffered lightning strike troubleshooting starting to explore the improvement measures for the lightning protection system to avoid the occurrence of similar situations.
